Evaluating the Influence of Various Forage Plant Varieties and Concentrate Additives in Milk Production and Quality in Cows
Abstract
The intention of this investigation is to examine the impact of specific forage plants and concentrated supplements on the quantity and quality of milk produced by local and crossbred cattle. A total of thirty lactating cattle, with an approximate body weight ranging from 300 to 350 kg and an age range of 5 to 11 years, were utilized for the investigation. The cattle were categorized into six groups, each consisting of five individuals. C1 and C2 were (local and crossbred cows, accordingly) exclusively fed with clover. C3 and C4(local and crossbred cows, respectively) were given a diet of both clover and sorghum stover. C5 and C6(local and crossbred cattle, respectively) were fed a combination of clover and concentrations. The findings indicated that the crossbred cattle in group C6 exhibited the maximum milk production (18.5k/day) compared to the other categories, with a significant difference (p<0.05). Following C6, group C5 had an average milk production of 13.9k/day. Groups C2, C4, C1 and C3 had average milk yields of 11.46k/day, 9.70k/day, 8.5 k/day and 8.7k/day, correspondingly. Regarding the milk elements, the experimental categories exhibited a notable variance (p<0.05) that can be linked to the kind of food and breeding.C (6) had the maximum fat content, measuring 6%, while C (3), (4) and (5) recorded fat contents of 4.5%, 4.7% and 5.7% sequentially. The dairy from C (1) and (2) exhibited the minimum fat level (3.7%) with statistical significance (p<0.05). The statistical assessment revealed a significant rise (p<0.05) in protein percentage for category (3) (6%), when compared to the other categories (1), (2), (4), (5) and (6), which registered protein percentages of 4.8%, 4.7%, 4.9%, 4.3% and 4.5%, respectively. The overall solids of C(1) and (2) were 13.4% and 13.6%, respectively, which were partially less (p<0.05) than the numbers achieved by cattle in C(3), (4), (5) and (6) of 14.7%, 14.9%, 14.7% and 14.9%, respectively. Furthermore, a substantial degree of variance was observed in the dust percentage clover (1) had a dust concentration. The liquid content of C (1) 89.5 and 90.9 C (2) was greater (p<0.05) compared to the other experimental groups C (3), (4), (5) and (6), which had water contents of 87%, 786.3%, 87.1% and 86.6% correspondingly.
