Introduction

 

Small ruminants diseases and nutrient deficiency are most eminent causes of production losses in goats (Yatoo et al., 2014). Nutrient deficiency results in poor growth, reduced pashmina yield, increased susceptibility to diseases and failure to conceive (Yatoo et al., 2014). Per animal production of 250-300 g of pashmina is far below than the inherited potential of 400 g (Yatoo et al., 2014; Wani et al., 2009). Production potential can be augmented by nutrient supplementation especially devised on area specific needs of animals and local feasibility (Yatoo et al., 2014; Yatoo et al., 2011). However, in Changthang such studies were lacking until recently we analyzed nutrient status of common fodders in Changthang and pashmina goats (Yatoo et al., 2016). Based on this nutrient status and local availability of fodders we devised area specific urea molasses mineral block (ASUMMB) (Yatoo and Kanwar, 2016). ASUMMB contains all essential nutrients including minerals and vitamins and provides maintenance requirements to pashmina goats and kids (Yatoo and Kanwar, 2016). Moreover, ASUMMB can serve as an alternate feeding supplement for goats (Ben Salem and Nefzaoui, 2003), hence, minimizing fodder requirements as fodder scarcity is one of the main limiting factors for production performance of pashmina goats (Yatoo et al., 2014). However, effect of ASUMMB supplementation on production performance of pashmina goats is yet to be elucidated. The current study was designed to assess the impact of ASUMMB on the production performance and overall health conditions of the pashmina goats.

 

Materials and methods

 

Study Area

Present study was conducted in Trans Himalayan Changthang region of Ladakh (J&K). The geo-climatic features of the area have been described previously (Yatoo et al., 2014).

 

Area Specific Urea Molasses Mineral Block (ASUMMB)

ASUMMB was prepared at KVK Nyoma, Leh by using dried and crushed mixture of local fodders/grasses (composite fodder), urea, molasses, mineral and vitamin supplements along with cereal bran including rice bran and wheat bran. These ingredients were mixed in a proportion based on nutrient status of ingredients so as to meet requirements of pashmina goats (Yatoo and Kanwar, 2016). The percentage of ingredients used for ASUMMB was molasses (38), wheat bran (15.3), rice bran (15.3), composite fodder (14.4), urea (5), cement (10), salt (1), and vitamin and mineral mixture (1).

 

Animal Selection and Management

Animals were selected from farmers herd maintained under similar managemental conditions. A total of 30 (N=30) pashmina goats, all of the age of 1.5-2 years and in their first kidding, were divided into three groups (Group I, II and III), each group having 10 (n=10) animals. Group I and Group II was supplemented with ASUMMB (150 g/day) and concentrate mixture (150 g/day) respectively, for 120 days (10 days of every month and regularly in the morning) each year. Group III was control with no supplementation. They were evaluated for body weight gain and health status on quarterly basis, pashmina yield and quality, conception rate and birth weight of kids, on yearly basis. At 2 months age, kids of these animals were divided into three groups (Group I, II and III), each group containing 6 animals (n=6). Group I was supplemented with ASUMMB (75 g/day) and Group II with concentrate mixture (75 g/day), both for 120 days in a year (10 days of every month and regularly in the morning). Group III was control with no supplementation. They were evaluated for body weight gain and health status on quarterly basis, pashmina yield and quality on yearly basis. Animals grazed in the same pasture for the same time during the entire period of study and had free access to drinking water.

 

Production Parameters

 

Body Weight: Animals were weighed before and after supplementation on quarterly basis each year by weighing balance (range 1-100 kg), after proper restraining of animal.

 

Pashmina Yield: Yield of pashmina was recorded at the time of shearing / combing on yearly basis by weighing with the help of weighing balance (range 1-500 g).

 

Staple/Fiber Length: After proper cleaning of combed/sheared pashmina, staple/fiber length was measured with the help of measuring scale (range 1-10 cm).

 

Health Status: Health status was evaluated by regular monitoring of animals and diagnosing diseases if any during the period of study.

 

Conception Rate: This was calculated by recording total no. of goats that conceived on first matting and gave birth to kid(s) after gestation period.

 

Birth Weight of Kids: Birth weight of pashmina kids was evaluated at the time of kidding using weighing balance (range 1-5 kg). Body weight and health status of pashmina goat kids was evaluated as described above.

 

Statistical Analysis

Data was analyzed by SPSS Software for repeated measure ANOVA followed by Tukey’s multiple comparison test. Statistical significance was assessed at p<0.05.

 

Results

 

Higher (p<0.05) body weight gain was noted in Group I of pashmina goats on month 3, 9, 12, 15 and18 of ASUMMB supplementation than Group III and on month 3, 12, 15 and 18 than Group II. Group II and Group III showed non-significant (p≥0.05) difference except on month 9, 15 and 18 (Figure 1). Body weight gain was higher (p<0.05) in Group I from month 9, 12, 15 and 18 than the initial months 0, 3 and 6. Group II also showed significant (p<0.05) body weight gain from month 9, 15 and 18. Group III showed non-significant (p≥0.05) change in body weight during entire study period.

Higher (p<0.05) pashmina yield was noticed in ASUMMB supplemented goats of Group I on12th month than the non-supplemented goats of Group III however concentrate fed goats of Group II showed non-significant difference (p≥0.05) (Figure 2).

 

Staple/fiber length was significantly (p<0.05) longer in Group I than Group II and III which differed non-significantly (p≥0.05) (Figure 3).

 

ASUMMB supplemented goats of Group I showed better health status (+++) from beginning (Day 0) to end (18th month) of the study than non-supplemented Group III (+) which also showed poor health status than concentrate supplemented Group II (++) (Table 1).

 

Conception rate was higher in Group I (100%) than Group II (80%) and Group III (60%) as all the 10 animals conceived in Group I, and only 8 and 6 animals in Group II and Group III respectively.

Higher (p<0.05) birth weight was noted in kids of goats supplemented with ASUMMB than the non-supplemented goats and concentrate supplemented goats (Table 2). Body weight gain was higher (p<0.05) in ASUMMB supplemented kids of Group I than non-supplemented kids of Group III and concentrate supplemented kids of Group II (Table 2). Health status was better (+++) in ASUMB supplemented kids than the non-supplemented kids (-) and concentrate supplemented (+) kids (Table 2). Significantly (p<0.05) higher pashmina yield and longer staple/fiber length was noted in kids of Group I than kids of Group II and Group III (Table 3).

 

Discussion

 

Nutrient supplementation through balanced feeding improves production performance and prevents deficiency (NRC, 2001). Hence increase in weight gain both in pashmina goats (14.79-27.11%) and kids (26.38-41.18%) due to ASUMMB supplementation can be related to balanced/

complete feeding hence amelioration of deficiency and provision of all essential nutrients required for normal growth especially of muscles and bones in young ones. Adequate nutrients including proteins and minerals in ASUMMB may have improved muscle and bone growth hence increase in body weight (NRC, 2001). Forsberg et al. (2002) have also reported increase in body weight due to urea molasses mineral block supplementation in goats. ASUMMB provides urea, a non protein nitrogen (NPN) which is utilized for protein synthesis and minerals which are used for bone formation (Kioumarsi et al., 2011) hence increase in body weight (Pinos-Rodríguez et al., 2011).

 

Increase in pashmina yield and staple/fiber length can be related to adequacy of nutrients for pashmina synthesis and development and appropriate fiber length attainment at maturity. Many nutrients especially proteins, copper, zinc have been found essential for animal fiber synthesis and development (NRC, 2001; Kincaid, 1999). ASUMMB provides all essential nutrients (Yatoo and Kanwar, 2016). However, Mulholland and Coombe (1979) have found no improvement in wool production on urea molasses mineral block supplementation in sheep.

 

Improvement in conception rate and birth weight of kids is attributed to better physiological and health status of pashmina goats due to adequate nutrient supplementation by ASUMMB. Better nutrition of goats enhances reproductive health, conception rate and increases birth weight of kids (Pinos-Rodríguez et al., 2011; Yatoo and Kanwar, 2016; Ceylan et al., 2008).

 

Normal health status of both pashmina goats and kids reflects better immune status of these animals due to complete/balanced nutrition provided by ASUMMB supplementation. Proper nutrition enhances immunity of animal (NRC, 2001; Arthington, 2006). ASUMMB supplemented goats showed non occurrence of any disease from beginning (Day 0) to end (18th month) of the study. However, two animals in non-supplemented Group III suffered from mild respiratory ailment and one animal in Group II had lice infestation during winter season which recovered spontaneously.

 

Significant difference in production parameters between ASUMMB supplemented Group I and non-supplemented Group III in different months may be attributed to adequate provision of nutrients in Group I and deficiency of nutrients in Group III resulting in better weight gain, higher pashmina yield with longer staple/fiber length, higher conception rate and better health status. Significant difference between Group I and Group II on latter months may be due supplementation of nutrients by both ASUMMB and concentrate feeding in the initial months of supplementation and balanced/complete nutrient supplementation by only ASUMMB over longer period.

 

Supplementation of ASUMMB to pashmina goats also resulted in higher birth weight and better health status of kids. These ASUMMB supplemented kids showed higher growth and pashmina yield with longer staple/fiber length and better health status than the non-supplemented and concentrate supplemented kids. This is in corroboration with Pinos-Rodríguez et al. (2011).

 

Supplementation of ASUMMB provides all essential nutrients in adequate quantities required for growth, development, production, reproduction and health (Yatoo and Kanwar, 2016). This may have resulted in improvement in physiological and developmental processes including body growth, pashmina development, conception and immunity.

 

Conclusion

 

Nutrient supplementation by feeding ASUMMB improves production performance of pashmina goats including growth, production, reproduction and health status. It also increases birth weight, growth and pashmina production of growing kids besides improving health status. Production performance of pashmina goats directly reflects the economic status of Changpas. Hence improvement in production potential of these animals can improve livelihood of poor pashmina farmers. Thus ASUMMB can be used as an alternate and locally feasible feed supplement for boosting pashmina production.
